There seems to be image issue with leofinance it seems. I can't see any image on the hive.blog front end.
As for course, I used to course hodler lol. not anymore. I can't even go back at code courses as they are dated now. So yeah youtube videos it is.
Apparently there's tons of issues with the API node they are using from Hive. They are getting their own one that should fix things I think.
